Now there's a new solution to one of the
most costly and troublesome problems facing maintenance personnel
- coupling failure and the expensive down time associated with fixing
it.
Only four parts to the Samiflex Coupling
The two identical hubs (items A & B)
are manufactured in cast iron, cast steel or aluminium alloy and
incorporate four, six or eight teeth, depending on size rating of
the coupling. A precision cast and machined polyurethane insert
(item C) fits between the hubs and is split axially so fitting and
removal can be achieved without moving hubs. The holding ring, manufactured
in steel, polyamide or bronze (item D) is fitted over the insert
securing both insert and ring between hubs. The coupling requires
no bolts or nuts.

Assembly & Disassembly
Once hubs (A) and (B) and holding ring (D) have been installed and
aligned on the shafts the coupling hubs will not have to be moved
again during the life of the equipment. The elastic insert (C) can
then be installed between the parallel slots formed by the hub teeth.
With the insert in position, slide the retaining ring (D) into position
over the polyurethane insert. Centrifugal force will expand the
insert under operation ensuring a tight, secure fit inside the retaining
ring.
Removing and replacing the coupling insert is very simple and requires
no special tools. By removing the retaining ring, the insert can
be quickly and easily removed and replaced without the need to undo
screws, bolts or other fasteners.
ATEX Approval
The range of Samiflex Couplings has been approved under ATEX directive 94/9/EC - for use in potentially explosive atmospheres.
